Facial expressions don't tell the whole story of emotion

Interacting with other people is almost always a game of reading cues and volleying back. We think a smile conveys happiness, so we offer a smile in return. We think a frown shows sadness, and maybe we attempt to cheer that ...

Robot circulatory system powers possibilities

Untethered robots suffer from a stamina problem. A possible solution: a circulating liquid—"robot blood"—to store energy and power its applications for sophisticated, long-duration tasks.

Blood flow

Blood flow is the flow of blood in the cardiovascular system.

It can be calculated by dividing the vascular resistance into the pressure gradient.
